or slider 7 which has an opening 8, which Be it known that I, TADnUsPAnAsnovicH, tray carries the powder under the funnel9 chemist, of Vienna IX, Apothekerhaus, and distributes it on the paper strip during rAustriaHungary, have invented a new and its |motion along the delivery channel 4. A useful Powder-Packing Machine, of which stirring device 10 prevents the powder from the following is 'a full, clear, and exact declogging in the neck of the funnel 9. scription.

This invention relates to devices for packing powdered material such. as drugs, chemicals and the like in determined quantities or doses of the type in which the wrapping ma: terial is fed into the device, the predetermined quantity of powder or the like is fed To all who-m it may concern:

st rip 3 two pins 11 are given longitudinal displacement through the agency of a bent shaft or the like, a connecting rod 12 and a lever 13, which pins as shown in Fig. 2 eX- tendl laterally over .the strip of paper 3. The upwardly projecting end of the paper strip 3 on the plate' is, by the swinging of the plate into position shown in dotted lines in Fig.'1, bent backward in such a manner that it lies above the strip of paper carrying the powder, whereupon the strip of paper is folded and guided between the rollers 15.

rlfhe pins 1l, which are provided with .meinbers which slide in the channel 16 of the work table are pulled outward at the end of the guide channel 16 against the action of a spring 17 so that they release the strip of the back swing pressing the edges together.

It has hitherto been proposed, in a device of the above type, to pass into the said device' a previously gummed strip of paper, which strip was folded over in the direction of its length and then passed between hot rollers carrying suitable projections which united the edges of the packet, after which the packet was cutolf from the continuous strip.

The invention has for its object an irnproved method of packing powdered drugs, chemicals and the like in any desired pack-l ing material such-as paper, wafers or the like, in which all the conditionsare fulfilled which should be observed from the hygienic point of view.

The invention consists substantially in an improved device for packing powders more particularly in doses or determined quantii ties, in which a previously unprepared wrapping material is fed into the device, the powder or the like being then fed on to the wrapper, after which one part of the wrap` pingniaterial is super-imposed on the part carrying the powder, and the edges of the two parts are finally secured together.

In the accompanying drawings are shown by way of example two constructional forms of the improved device. f

Figures 1 and 2 illustrate the device in side elevation and plan respectively.

As lillustrated in the drawings, a band of paper whereupon the pins on of the lever 13 are restored to their initia position by means of the said member sliding in the outer part of the" guide channel 16, where they are again pushed over the paper strips with their inner ends, against the action of the spring 1S. As soon as the paper strip is gripped by the guide rollers 15, a slide 2O reciprocating up and down between guides 19 and carrying a knife blade has attained its lowestposition and separates the paper strip containing the powder from the remaining portion of the paper, this motion of the slider 20 vbeing effected by means of the disk 21, a lever and a draw rod 23. The free end of the paper strip is thereupon advanced through the rollers 2 on the plate 6 which has resumed its upward position by device gives another supply of owder. The rollers 15 now bring the cut o containing the powder under the rollers 24 which as shown in Fig. 2 are provided near paper 3 from a roll 1 passes between guiding the edge with teeth which connect together rollers 2 below the delivery channel 4 of the the covering. strip and the underlying strip by means of their perforating action. addition to the lateral teeth 25 perforating teeth 26 are also arranged along a generating line of the cylinder, by means of which the third open side of the packet is closed in the same manner as the side edges. From the rollers 24 the packet arrives on an obmeasuring or distributing apparatus 5. The end of the band 3 lies on a plate 6 pivoted'to the framework of the mechanism. The distributing apparatus 5 which is not a feature of the present invention may be of any suitable construction. The type illustrated in the drawing possesses a reciprocating tray Patented sept. 10,1912.

1When the powder has been broughton the i paper strip plate, means for depositingra predetermined plates the mechanical fastening of the free gins to interlock the same, and that subselique `downwardly directed plane 27 below which may be provided a suitable receptacle for the prepared packets of powder. .lnstead or' perforating the edges gumming rollers may be provided between the guide rollers 2 and the distributing apparatus, by means of which the side edges of the strip are smeared with adhesive. In this case the rollers 15 would be designed as pressure rollers to enable the gummed side edges to be pressed together and the packet thus kept in closed condition.

For the driving of the moving parts a handle 28 is provided in the modiiication illustrated by means of which the shaft ll may be rotated. On this shaft are mounted on one side the finger disk for the actuation ot' the slide, of the distributing device, and the knife slide 20, also the cranks or bends to which are attached the connecting rods l2 `for the actuation of the pins 14. Gn both sides lnea`r the ends of the shaft 11 is mounted a groovedldisk Q9 over which the driving cord 30 for the actuation of the guide rollers and perforating rollers, is assed. This cord fi() is led from the drivingidisk 29 over the lower of the two guide rollers 2 a roller 3l to a tensioning {'oller 32 adjustable from the exterior from which the cord passes over the lower perforating roller 24 the lower :ulvancing roller 15, the guide rollers 33 and 34 and returns to the driving disk 29. In this way it is possible to set all the moving parts of the device in action from the driving shaft 11.

Instead off a hand drive the device may be driven by power, by an electric motor for example or the shaft 11 set in rotation in any other manner.

It will be seen that my invention contemend margins, and the free margins of one side of the wrapper, with the said margins in flat abutting relation and in a flat osition. It will therefore be seen that only one fold of the paper is necessary and that I dispense with folding operation in connection with the fastening of the margins.

It will also be noted that the perforating means 25, successively engages the end marquently, the perforating means 26, simultaneously engages the free margins of the side to interlock the same and to completethe connection to form a packet with interlocked margins.
